Northern Sphere Mining Corp. Optimizes Mineral Targets on its Sudbury Nickel Belt and Arizona Porphyry Copper Properties

During 2017, Northern Sphere focused on mineral discovery using exploration techniques on a district scale at both its Canadian and U.S. properties. In addition to using remote sensing tools, including high resolution hyper-spectral imaging, the Company used 3D magnetic re-inversion methods to re-interpret and model three-dimensional geophysical data. Combining these new results with geochemical soil surveying, prospecting, diamond drilling, Northern Sphere has identified multiple new mineral targets.

In 2018, Northern Sphere will continue with this program and also plans to incorporate machine learning into its exploration efforts.

Northern Sphere will continue to advance and acquire district scale properties for successful future mineral exploration.

Scadding Mine - Past-Producing Mine Extensive Historical Drilling & Associated Data

• Existing underground ramp to access higher grade zones
• Poorly understood deposit at depth: limited drilling to depth >~150m
• Close relationship between diabase intrusive bodies and mineralization
• Further testing of the North zone in 2017 revealed high (>13 g/t) gold content over significant (>10 m) length
